6 grams should be noticeable in the same mold of the same plastic. Lighter discs of the same mold and weight flip easier. This means that a beefy enough mold in light weight won't flip. There might be some weight discussion in the 150 lovers thread. Blizzard discs are light and retain the stability of the same mold in other plastics of 15-20 grams more weight. So they rewrite the old rules to some extent. Blizzard vs Blizzard of different weight seems to follow normal rules.

Flat shots need running on the center line of the tee and planting each step on the center line. Anhyzer needs running from rear right to front left with the plant step hitting the ground to the left of the line you're running on. Hyzer is the mirror of that.

I have a surgically operated arm that is unrepairable to full condition so i'm not a power house by any stretch of the imagination. For gimps and old gits like me 150 is great news even before Blizzard era. I get at least 20 probably 30' more with the 150 Teebird than a 175.
